Because we no longer linkToDeath against a binder object to detect if
the cmd process has died, we detect deaths by checking if writes fail.
ag/10476582 proves that writes fail if the cmd process dies.

Major changes include:
- Removing unused permission checks within StatsService. These
include ENFORCE_DUMP_AND_USAGE_STATS, checkDumpAndUsageStats,
kOpUsage, and kPermissionUsage.
- Converting from sp to shared_ptr
- Using libbinder_ndk functions instead of libbinder functions
(e.g. for installing death recipients, getting calling uids, etc.)
- New death recipients were added in StatsService,
ConfigManager, and SubscriberReporter.
- Using a unique token (timestamp) to identify shell subscribers
instead of IResultReceiver because IResultReceiver is not exposed by
libbinder_ndk. Currently, statsd cannot detect if perfd dies; we
will fix that later.

1) Refactor pullers and add tests.
2) Add timeout to a puller.
mPullTimeoutNs is intrinsic to puller. A pull taking longer than this is
deemed failed and the data discarded.
A metric or StatsPullerManager requesting a pull should monitor the pull
and have deadlineNs. A successful pull may come later than desired due
to statsd processing delays.
3) Add unit tests to puller now that the base puller is more
complicated.

+ Changed the output format from Atom to ShellData, which is a wrapper for repeated Atom
This is useful because pulled atoms are usually a list of atoms.
